Description
Technical Field
The invention relates to the field of manufacturing of optical fiber panels, in particular to a dispersion arrangement method of large-size optical fiber panels.
Background
The optical fiber panel product is an optical fiber image transmission element made of special glass optical fibers, small-size optical fibers are drawn by a prefabricated tube, and then the small-size optical fibers are subjected to repeated arrangement, combination and drawing processes for many times and finally are subjected to fusion pressing and molding.
In recent years, higher requirements for the size of optical fiber panels have been made in the fields of night vision attachment systems, screen displays, and the like. For example, a certain type of optical fiber panel having an image transmission area of 500 × 300mm, which is 160 times the area of a conventional optical fiber panel, has 70 billion optical fibers inside, and needs to arrange about 30 ten thousand composite optical fibers. Such a large number forces us to review the alignment method.
The existing optical fiber panel optical fiber arrangement method is: firstly, selecting a proper arrangement mould according to a product optical fiber arrangement drawing; secondly, an operator sequentially grabs 1-10 composite optical fibers and places the composite optical fibers in an arrangement mold; thirdly, after the position and the angle of the composite optical fiber are adjusted, next grabbing and arranging are carried out, and each arrangement is carried out layer by layer from left to right and from bottom to top; fourthly, bundling the products after finishing the arrangement of one product; and fifthly, manually taking out the bundled semi-finished products, and transferring the semi-finished products into a melt-pressing mould for melt-pressing. The alignment process is shown in figure 6.
However, the existing optical fiber arrangement method has the following disadvantages:
when the method is used for arranging the optical fibers, an operator needs to continuously arrange hundreds of optical fibers in the die, wherein the optical fibers are required by the product. The arrangement mode is suitable for small-size optical fiber panels, and for large-size optical fiber panels with the area being hundreds of times larger, the arrangement mode occupies several times of the original time, so that several days are possibly needed, and the production efficiency is too low. Meanwhile, the optical fiber is exposed to the external environment for a long time, and the index requirements of the optical fiber panel such as chromatic aberration and internal quality are further influenced.
When the manual bundling mode is used for a large-size optical fiber panel, the problems of loose bundling, dislocation of a composite optical fiber structure and the like can occur.
The transfer process after finishing the arrangement is dangerous, the weight of the optical fiber panel with larger size can reach dozens of kilograms, and the optical fiber panel can not be taken out artificially and naturally.

B. turning the sub-mold by 90 degrees, placing the sub-mold on a transfer device, and adjusting the transfer device to ensure that part of the sub-optical fiber panel protruding out of the inner cavity of the sub-mold extends into the inner cavity of the mother mold;
C. the baffle plate positioned at the side part of the sub-mold is pulled out, and the sub-optical fiber panel in the sub-mold is pushed out, so that most of the sub-optical fiber panel extends into the inner cavity of the mother mold;
